Question

How do snails, seeds, bears, zooplanktons, fungi and bacteria adapt to conditions unfavourable for their survival? [3]

Answer 1

Snails adapt to unfavourable conditions by producing epiphragm during aestivation that covers the opening of its shell and thus prevent desiccation. [0.5]

Seeds adapt to unfavourable conditions by getting into a state of dormancy or suspended metabolic activities. [0.5]

Bears adapt to unfavourable conditions by hibernating and reducing their body metabolic activities by about 75%. [0.5]

Zooplanktons adapt to unfavourable conditions by entering into diapause, a stage of suspended development. [0.5]

Fungi adapt to unfavourable conditions by reducing their metabolic rate and by forming thick-walled spores. [0.5]

Bacteria adapt to unfavourable conditions by forming endospores. [0.5]
